I am currently using Hasport 88A engine mounts with JimFab front mounts. Recently, I am thinking of a header (AN-R, Bisimoto style) which might interfere with the left front mount (A/C mount).

In the event that it does and such mount needs to be removed, would the other 4 be strong enough? In my humble opinion, these are pretty much the hardest mounts on the market compare to stock.

Car is used for road racing, and some daily driving. I have searched and most suggested leave that in (using all 5), but that is based on stock mounts, not aftermarket mounts.

Thanks

 

I know a number of people (including myself) who use only the three HASport mounts. I haven't had any problems...yet. While it does worry me a little, just because of logic, my understanding is that those front mounts are mostly for NVH control.
